No more hunting for cakeboxes! These PVC shrink tubes are perfect to package 100 discs. All you need is a spindle and a heat gun to make a tube of 100 discs. You can also cut the tube to smaller sizes to package fewer discs. This item is perfect for duplicating companies who often have to package bulk discs. This SKU contains 500 shrinktubes. The material is 20 micron PVC so it's best to double them up if you're shipping them.
